Step-by-step explanation:

Given:

The area model for [tex]2.1\times 3.2[/tex].

To find:

The value of [tex]2.1\times 3.2[/tex] and the missing values in the area model.

Solution:

2.1 can be written as 2 and 0.1 on the left side of the area model.

3.2 can be written as 3 and 0.2 on the top of area model.

Area of the four parts of the area model are:

[tex]2\times 3=6[/tex]

[tex]2\times 0.2=0.4[/tex]

[tex]0.1\times 3=0.3[/tex]

[tex]0.1\times 0.2=0.02[/tex]

The complete area model is shown below.

After adding all areas of the area model, we get

[tex]6+0.4+0.3+0.02=6.72[/tex]

Therefore, the value of [tex]2.1\times 3.2[/tex] is 6.72 and the missing values of the area model are 0.3 and 0.02 respectively.

Answer:

3a+5b

Step-by-step explanation:

Variable 1:  a = candy corn

Variable 2: b = chocolate

Inequality 1:  60 ≥ 3a + 5b

Inequality 2: 20 ≤ 3a + 5b

The inequalities are as such because Josh needs to spend no greater than $60.  He must also buy at least 20 bags of candy.  The candy corn costs $3, while the chocolate costs $5.  An expression for the total cost of the candy would be 3a + 5b.

Answer:

Answer:

10.93

Step-by-step explanation:

5.9 ÷ 0.54 = 5.9 x 1/0.54 = 5.9/0.54 = 10.93

Answer:

m<A=94

Step-by-step explanation:

(2x+10)+(2x+2)=180

4x+12=180

-12 -12

4x=168

/4 /4

x=42

m<A= 2x+10

m<A=2(42)+10

m<A=84+10

m<A=94

Check:

Add m<A and m<B which should equal 180.

m<B=2x+2

m<B=2(42)+2

m<B=84+2

m<B=86

94+86=180

Answer:

The probability is 1/24

Step-by-step explanation:

For a 12-sided dice, there are 12 different possible results

so the possibility of rolling a 7 is just one of the results

The probability of this is simply 1/12

For landing on head, the probability is 1/2

So the probability of the event occurring is the product of these two events

We have this as;

1/2 * 1/12 = 1/24

Answer:

x/x+1

Step-by-step explanation:

[tex]\frac{4n}{4n-4} * \frac{n-1}{n+1}[/tex]

start by reducing the 4n-4 by distributing the 4 to make it 4(x-1)

So the fraction would be 4n/4(x-1)

Now that you have done that you can easily take off the 4 as well as the x-1 thats now in the parentheses

The new equation would be

n*n-1/n+1

Now just multiply:

x/x+1

Answer:

B.) n/(n+1)

Answer: l=50 m, w=20 m

Step-by-step explanation:

Given

A rectangular city has an area of [tex]1000\ m^2[/tex]

Also, length is 10 m more than twice its width

suppose width is w

So, length is given by

[tex]\Rightarrow l=10+2w[/tex]

The area is given by

[tex]\Rightarrow A=l\times w\\\Rightarrow 1000=(10+2w)\times w\\\Rightarrow 2w^2+10w-1000=0\\\Rightarrow w^2+5w-500=0\\\Rightarrow w^2+25w-20w-500=0\\\Rightarrow (w+25)(w-20)=0\\\therefore w=20\ m\\l=10+2w=10+2\times 20=50\ m[/tex]

Answer:

x = 6

Step-by-step explanation:

3x + 4 = 22

subtract 4

3x = 18

divide by 3

x = 6

Answer:

x=6

Step-by-step explanation:

Subtract 4 from each side of the equation to get 3x=18. divide 18 by 3 to get 6, and divide 3x by 3 to get x. x=6

Answer:

9500

Step-by-step explanation:

Scientists tagged 950 pike for a research project about a local lake. Later, they trapped 100 pike, of which 10 had tags. To the nearest whole number, what is the best estimate for the pike population?

The best estimate of a population is calculated as:

= N = mn/k

Where N = Estimate of the population

m = 950 pike

n = 100 pike

k = 10 tags

= 950 × 100/10

= 9500

The best estimate of he population = 9500

Answer: problem 1 A

Step-by-step explanation:

Answer:

60 degrees

Step-by-step explanation:

s = r (theta)

(theta) = s/r

= 1 / (3/π) = π/3

as a degree π/3 x 180/π = 60

60 degrees

*Circumference = 2πr

6 = 2πr

r = 6/2π = 3/π

Answer:

C)

[tex] \frac{1}{2} [/tex]

Step-by-step explanation:

Your problem should be set up like so:

[tex] \frac{1}{6} \div \frac{2}{6} [/tex]

When dividing fractions you multiply by the reciprocal of the second fraction. Therefore your question changes to this:

[tex] \frac{1}{6} \times \frac{6}{2} [/tex]

You multiply as across as normal and you'll end up with

[tex] \frac{6}{12} [/tex]

Which when simplified gives you

[tex] \frac{1}{2} [/tex]

Answer:B i think if wrong im so sorry

Step-by-step explanation:

Answer:

B 75+25h

Step-by-step explanation:

$75 is the first charge for the service and is constant. $25(per hour) is not constant and changes as the time (hours) changes. That's why it has a h next to it, the h is the variable to hold the place for the hours that would be multiplied in the problem.
